SUPPORTING-BRACKET FOR CURTAIN-ROLLERS.

SPECIFICATION forming part of Letters Patent No. 625,429, dated May 23,1899. Application filed November 19, 1897. Serial No. 659,118. (Nomodel.)

T 0 all when), it ntrty concern:

Be it known that I, EDGAR J. THACKER, a citizen of the United States,residing at St. Louis, State of Missouri, have invented certain new anduseful Improvements in Supporting-Brackets for Curtain-Rollers,of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in supporting brackets forcurtain rollers; and it consists in the novel arrangement andcombination of parts, more fully set forth in the specification, andpointed out in the claims.

In the drawings, Figure 1 is an elevation of my bracket, showing acurtain suspended therefrom. Fig. 2 is a section on line 2 2 of Fig. 1,showing the canrdisks, however, in elevation. Fig. 3 is a section online 3 3 of Fig. 2, showing one of the cam-disks in elevation; and Fig.4: is an end view of one of the coupling-sections.

The object of my invention is to construct a bracket which is adjustableas to length, thereby enabling the same to be supported from awindow-frame of any width and be used in connection with a shade-rollerof any length.

A further object is to construct a bracket which will be simple, cheap,durable, and light.

In detail the invention may be described as follows.

The device is constructed of two wire lengths 1 and 2, respectively,coupled in a manner to be now described.

3 represents a substantially oblong packing-plate whose face and endsare snugly embraced by a band or casing l, formed from an originaloblong plate or metallic strip, the free ends of the band having theiredges bent outwardly, as at 5 5, and meeting substantially along amedial line of the packing-plate 3, the said outwardly-deflected edgesforming thus a guideway for the reception of a locking-tongue 6,havinginwardly-deflected edges 7, embracing the edges 5, and being,furthermore, provided with terminal lobes or cars 8, which aresubsequently bent around the ends of the casing thus formed by the band4. and against the front wall of said oasin g. In this way thepackingplate 3 is snugly confined within the band or casing so formed,except that a sufiicient space is left between the opposite ends of thepacking-plate and the adjacent walls of the casing for the insertion ofthe wires, as subsequently to be described.

The packing-plates, with their inclosing bands, are for conveniencedenominated herein as the couplingsection. At points adjacent theopposite ends of the packing-plates the walls of the band are cut awayto allow for the free passage therethrough of a cam-disk 9, each diskoperatin gin a suitable depression 10 cut in the ends of thepacking-plate. The free end of the upper lap of the wire 1 terminates ina hook 11, which embraces the cam-disk car ried by the right-handcoupling-section, the wire passing between the end of the packingplateand the band surrounding the same and the hook itself snugly embracingthe camdisk. The upper lap of the wire thence eX- tends to the left,passing loosely and eccentrically through the cam-disk of the left-handcoupling-section and between the casing and adjacent end of thepacking-plate, thence passing through a terminal casing or section 12,hugging the inner walls thereof, the wire emerging at the top in theform of a loop 13 and at the bottom in the form of an arm 14,terminating in a hook 15, forming a support for one end of theshade-roller 16, thence emerging from said section in a second or lowerlap parallel to the first lap, passing eccentrically through the lowercam-disk of the left-hand coupling-section, and then entering theright-hand coupling-section and terminating in a hook 11, embracing theinner portion of the cam-disk 9 and terminating at a'point adjacent tothe end of the easing. The wire 2 describes substantially the same pathas wire 1, except in a reverse directionthat is to say, the terminalhook 11 of the lower lap thereof embraces the exposed portion of thecam-disk of the left-hand coup ling-section, thence emerging from saidcoupling-section and passing loosely and eccentrically through the lowercam-disk of the right-hand coupling-section, thence through theright-hand terminal casing or section 12, forming a loop 13, thencepassing eccentrically through the upper cam-disk of the righthandcoupling-section and terminating in a hook 11, embracing the innerportion of the upper cam-disk of the left-hand coupling-section. Theterminal sections 12 need no packing-plate, but are directly bent aroundthe wires passing through them. In order not to expose the verticalterminal length of the wire passing therethrough, each section 12, orrather the strip from which same is bent, is provided with a tongue 17,which is bent around the same, the adjacent end of the locking-tongue 6abutting against the edge thereof when once bent into position, thetongue 6' being providedat the terminal sections with but a single lobe8', bent across the inner end of the section or'casing 12 and againstthe front wall thereof. The casings 12 are otherwise cut away at thecorners to expose the wire passing therethrough and giving the same aneat finish. The eyes 13 serve as means of securing suspending-cords19,which may be passed through eyes or hooks 20 along the window-frameand terminate in' the tassels 21, weighted sufficiently to balance thebracket and curtain suspended therefrom.

Loosely embracing the upper laps of the respective wires are castings orsupplemental brackets 22, from which the en tire device may be suspendedshould the frame of the window be too narrow to permit the suspensionthereof in cases where the roller 16 was too long for the width of suchframe.

It is obvious from the foregoing that the laps of each wire serve as anaxle about which the cam-disks can be rotated, the latter serv-- ingwhen turned in proper direction to grip the hooked ends 11 11 ll of theadjacent laps of the second wire, and it is also 0bvious that as thecam-disks are turned in proper direction to release their grips theterminal sections or casings 12 may be shoved either to or from eachother, thus bringing the coupling-sections to any predetermined distance(see dotted position in Fig. 1) and varying the length of the device asa whole. It is apparent, of course, that the distance be tween eachcoupling-section and its corresponding terminal section is constant.Each cam-disk is preferably made with an outer sectional shell, the twohalves embracing a suitable elastic filling or packing 9, as best seenin Fig. 3, the packing serving to hug the wire about which the diskrevolves. I

It is obvious, of course, that the device might be altered in detailwithout departing from the spirit of my invention, and it is alsoobvious that it may be used in other connec- Lions than thatspecifically herein referred tosuch, for example, as a towel-bracket,shade-bracket, and in other relations where its functions are notmaterially altered.

From the foregoing it is apparent that one coupling-section while freeto slip over one wire is permanently coupled to the other by the hookedends 11 11 11" of the second wire.

Having described my invention, what I claim is 1. A curtain-rollerbracket, comprisingtwo coupling-sections, each section composed of aninner packing-plate, and a band or casing embracing the same, theopposite ends of the plates being recessed, and the walls of the casingbeing cut away, cam-disks inserted into said cut-away portions andrecesses, a wire length having one lap passing between the walls of theband and adjacent end of the plate, and formed at its end into a hook,embracing the cam-disk from the outside of the casing, said lap thencepassing loosely and eccentrically through the corresponding disk of theadjacent coupling-section, the second lap passing similarly through theopposite camdisk of the same coupling-section, and finally terminatingin thefirst coupling-section, and embracing the opposite cam-disk of thefirst section along the inside thereof; a second wire having two laps,passing similarly through and embracing the several cam-disks referredto, but in a reverse manner, that is to say, passing loosely through thedisks embraced by the first wire, and embracing the disks looselypierced by the said first wire, each Wire extending a suitable distanceexteriorly of the coupling-sections, the parts farthest removed from thecoupling-sections being bent into depending arms formed into hooks attheir free ends for the support of the opposite ends of a suitableshade-roller, the parts operating substantially as and for the purposeset forth.

2. In a curtain-roller bracket, suitable intermediate coupling-sectionsunited by two wire lengths, cam disks carried by each coupling -section,an interior packing-plate forming a part of each coupling-section andrecessed for the partial reception of each camdisk, and terminalsections or casings through which the bends of the wires constitutingthe opposite ends of the bracket, are passed, substantially as setforth.

3. In a curtain-roller bracket, suitable sections, formedof bands havingat their meeting ends outwardly-deflected edges forming guides, lockingstrips or tongues having inwardly-deflected sides cooperating with saiddeflected edges, interior packing-plates for the sections and terminallobes or ears for embracing the ends and the peripheral walls of thesections, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
